... *sigh*
ANY DirectX code is windows only. They won't port it to the PS4 because the PS4 doesn't run windows. They will port the openGL version (if at all).
Yes, that's about it. All newer GPUs are DX11 compatible, so if they implement DX11 features your GPU will automatically use it. At least most games detect which mode they have to launch in automatically, from what I saw.
Well, it's one thing if your GPU/CPU is running at 60fps and using only 30% of the resources (= hardware "too powerful" for the game), and completely another when it stutters like hell while not using all of the resources (= bad optimization)I see people "complaining" that they "only" get a 30% CPU load, as if they want their processor to be doing 80% or something. Similar complaints with GPU use. This confuses me. Do they WANT their computers to work harder?
